Natural Variation in Handwriting

It is a graphical identity obtained by a person through symbols or letters that may or may not correspond to his name which gives authenticity to document. The signature is generally a persons most common writing act. And it is largely habitual. As there are no rules for devising and producing signatures, they are highly individualized according to each persons mental design. Often deliberately formulated, the persons signature serves as a "TRADE MARK". Signature can be written as illegible shapes or series of clearly decipherable letters that distinctly spells out the persons name. in many cases they have no resemblance to the writers name at all, but they are merely identifying marks. In any case their construction and execution are relatively stable and their features more or less subconsciously produced. Due to their repetition writing strokes and formation that comprise persons signature are generally consistent, even over long time spans.
